Is Praxis 5436 required in every state?

No. Praxis requirements are established by individual states and licensing agencies.

Some states require Praxis 5436 for a general science teaching license. Others may use Praxis 5442 Middle School Science, Praxis 5236 Biology or a state-developed science assessment.

Do not register based only on information from a preparation website. Confirm the examination code directly with the responsible licensing authority.

How many questions are on Praxis 5436?

Praxis 5436 contains 135 questions.

ETS notes that the examination may include questions used for research or future test development that do not count toward the reported score. Because candidates are not told which questions are unscored, every question should be treated seriously.

How long is Praxis 5436?

Candidates receive two hours and 30 minutes, or 150 minutes, to complete the examination.

This provides an average of approximately 67 seconds per question. Some questions involving graphs, experiments or teaching scenarios will require more time than direct knowledge questions.

Candidates should practice moving efficiently through easier questions and returning to more demanding questions when time permits.

Praxis 5436 Scoring FAQs

What is the passing score for Praxis 5436?

There is no single national passing score.

Each state, licensing agency or educator-preparation program establishes its own qualifying score. Confirm the current requirement through the ETS state requirements directory and your licensing authority.

AIProctoredExams also provides state-specific guidance, including:

Always confirm scores against the licensing agency’s latest requirements.

How is Praxis 5436 scored?

The raw score is based primarily on the number of scored questions answered correctly.

ETS converts the raw result into a scaled Praxis score. Because different examination forms may vary slightly in difficulty, there is no permanent conversion showing that one exact number of correct answers always produces the same scaled score.

How many questions must I answer correctly to pass?

There is no guaranteed number of correct answers that applies to every test form and jurisdiction.

The result depends on:

Your state’s qualifying score
The number of scored questions
The statistical conversion applied to the test form
Your performance across the examination

Practice-test percentages are useful for measuring progress, but they should not be treated as guaranteed scaled Praxis scores.

Will I receive an unofficial score, and when is the official score available?

Because Praxis 5436 consists of selected-response questions, candidates are generally offered an opportunity to view an unofficial score after completing the test.

An unofficial score might not appear when ETS requires additional analysis. This does not necessarily indicate a testing problem.

Official results are posted in the candidate’s Praxis account according to the score-reporting schedule. The reporting date depends on the test date and delivery method. Use the official Praxis score-reporting tool to check the expected date.

How long can I access my Praxis scores?

For scores reported on or after July 21, 2017, ETS states that downloadable score reports generally remain available in the candidate’s Praxis account for ten years from the reporting date.

Download and save a copy for teacher-certification, employment and personal records.
